<p>A pneumatic tire 1 according to the present invention comprises a plurality of land blocks 10-14 defined by circumferential grooves 2-5 extending in a tire circumferential direction and lateral grooves 6 extending in a tread width direction, wherein a stepped portion 10a-14b extending in the tread width direction is provided at at least one of circumferential edges of each of the land blocks 10-14. The stepped portion 10a-14b is formed to have the same width dimension as a width of the land block. A height of the stepped portion l0a-14b is the smallest for the land block 12 closest to a tire equator line CL and becomes gradually larger toward an outer side in the tread width direction. A maximum height of the stepped portion 10a-14b is smaller than a height of a tread surface Tr of the land block 10-14.</p> |
